@tomcctv ...the most knowledgeable on this forum? Seriously? Dude, from what you wrote in this thread, it looks like you have absolutely no knowledge in topic. You have been given links to certain information by other users, but you haven't even spent a second to read this. There is no such thing as pixel size? It's like saying "The Earth is flat, because it looks like flat". Starlight is Dahua's technology? I can't choose if to laugh or to cry. I could give you plenty of links to prove you are wrong. But I know it's useless, because you won't read any of these. If not the number of posts under your avatar I would think you are just trolling. Buy it seems you really believe in what you write. That is sad.
